Description: It has a woolly, spiny apex; the ribs are slender deeply notched wavy and corrugated; Areoles are at first covered with white felt. The beautiful crested form is very rare in collection and highly priced.
Spines: Centrals 1 or 2 (to 4), growing one above the other, which of variable length up to7 cm. long. They are sharp and needlelike, sometimes flattened, pointing upward at first and then outward, brownish-black at their apex and somewhat reddish lower down. Radials (10 to) 15 to 25 slender, almost transparent white, 1-1.5 cm long straight or slightly curved, and radially arranged, overlapping each other above the ribs.
Flowers: The flowers are 2 (2,5) cm. long, often remain squeezed between the apical spines, and have pale yellow, creamy-white or pink segments with a darker mid-stripe.

Cultivation and Propagation: It is a fairly easy plant to grow both grafted or in its own roots. During the summer it is best to keep the plants outside where the temperature can rise to over 30 C with no harm to the plant. Furnish good drainage and use a an open and free draining mineral compost that allows therefore roots to breath. They like only a short winter's rest and should be kept almost completely dry during the winter months, If the soil is allowed to be dry for too long root loss could follow but equally the same result would occur if the plants are both wet and cold. From March onwards the plant will begin to grow and watering should be increased gradually until late May when the plant should be in full growth.
Water regularly during the summer so long as the plant pot is allowed to drain and not sit in a tray of water. During hot weather you may need to water the plants more frequently so long as the plant is actively growing. From late September watering should be reduced to force the plant to go in to a state of semi dormancy, by October you should be back in to the winter watering regime.
Need full sun avoiding only the harshest summer sun, if kept too dark they may become overly lush and greener and could be prone to rotting due to over watering.
Feeding may not be necessary at all if the compost is fresh then, feed in summer only if the plant hasn't been repotted recently. Do not feed the plants from September onwards as this can cause lush growth which can be fatal during the darker cold months.
Propagation: By vegetative propagation grafting or stem cuttings from adult plants.
